CONTAINER-SPOUT.

Application filed June 17, 1916. Serial No. 104,300.

T 0 all whom it may concern:

Be it known that I, FRANCIS C. OSBORN, a citizen of the United States, residing at Detroit, in the county of WVayne and State of Michigan, have invented a new and useful Container-Spout, of which the following is a specification.

his invention relates to pouring spouts for containers and more especially to spouts of containers of powdered or granular substances such as baking powder, salt, coffee, etc, and which it is desirable to collapse in order to close the containers to keep the substances from exposure, and which, when closed, are practically flush with the surface of the container in order that the packages may be closely packed together for shipment or storage. Its objects are, to fur nish an improved form of spout which is held in place by an improved form of hinge, to provide means whereby the opening for the spout is more completely sealed, and

such other improvements as are set forth in the claims.

The nature of the invention will be more fully understood from the following description and accompanying drawings, in the latterof which: Figure 1 is a plan view of a blank before being formed. Fig. 2 is an end view looking at the lower edge of the same blank after forming. Fig. 3 shows a container cover ready for the insertion of the spout. Fig. 4 shows a blank the same as in Fig. 1 with points struck upfor fastening a fiber sealing piece thereto. Fig. 5 shows a metal container cover ready for the insertion of spout shown in Fig. 4., with fiber lininfg around the openings for sealing same. i 6 is a section of Fig. 5 on line X-X. igs. 7, 8 and 9 are modifications of the spout. Fig. 10 shows the form of spout shown in Fig. 9 in place in a cover. Fig. 11 is an end view of Fig. 9, looking at the lower edge thereof after the blank is formed and in place. Fig. 12 is an enlarged section of one of the points d bent up to hold the fiber lining. Figs. 13, 1 1, 15, 16 show various forms of bending the hinge portion 1. V

Similar reference characters refer to like parts throughout the several views.

In the embodiment of my invention shown in Figs. 1 to 3 inclusive, I form a spout from a single piece of sheet metal, preferably, although other material may be used, approximately semi-circular in contour, of

which the portion A forms the top or closure when in place in closed position and one of the sides of the spout when open,

and-the part B constitutes a wing or guide for holding the spent in position when closed and the other side of the spout when open. The projections 1, 2 and 3 are integral with A and B andare formed from- I and forms a stop against further opening of the spout. The projection 1 may be bent as shown in Figs. 13, 14 and 16, or may be used rnbent as shown in Fig. 15. In the latter case the wall of the container is formed as shown in Figs. 3 and 15 at 5. Fig. 3 shows a container cover, preferably of paper fiber, top side up ready for the insertion'of the spout shown in Fig. 2. The lugs or projections 2 and 3 are bent to the angle shown in Fig. 2 after the spout is inserted in the cover. The projecting portion of the cover 4, furnishes a supporting shoulder which cooperates with lugs 1 and 2 to form the hinge. This shoulder may be bent downward slightly. The edge of the part A between lugs 1 and 2 is in the axis upon which the spout revolves. The opening 6 in the cover is constricted by the bentdown portions 7 and 8. These serve to prevent too much material from coming out at one time but by being bent downward and being resilient they permit any excess of material not falling back into the container through the clear opening when. the spout is being closed to be pressed below the surface thus not interfering with the complete closing of the spout or being spread over the cover. This is very likely to happen with the ordinary construction, especially when the container is quite full as the material is shifted and piled up on the spout side of the container as it is held in pouring position and does not fall back into place unless sharply shaken to make it do so. The depression 9 is for facilitating the opening of the spout by enabling a finger nail to be inserted under the edge of the spout. It is exceedingly dificult, if not impossible, to insert a metal spout in a metal container, by the ordinary method, so as to prevent air circulation and hence oleteri0ra-' tion of the contents of the container. In order to overcome this difiiculty I provide a fibrous lining or packing to the metal container around the opening for the spout, and. in Figs. 4, 5, 6, 7 and 12 is shown one method of arranging and applying this packing to the container and the spout. The points or tongues d are struck down in the metal as shown, and the fibrous packing, outlined by the dotted lines in Figs. 4 and 5, is'secured to the container as shown in Fig. 5 in the manner shown in Fig. 12 by bending the tongue forward under the opening from which it is struck to prevent any opening around the tongue. The blank shown in Fig. 4 is now put in place after being bent at right angle on the vertical dotted lines and the tongues oZ pressed into the openings at and clenched as shown in Fig. 12. The portion of the packing fastened to the spout is preferably integral with the rest of it and may be used as a hingei'or the spout and the lugs 1 and 2 and the part 4 may be dispensed with, but I prefer to use in addition the hinge lugs l and 2 as shown. The fibrous packing lining thus serves to furnish a close fitting joint at all parts of the opening in the metal coverwhen the spout is closed. It will be noted that the fibrous packing is shown in one piece, and by proper change in form may be adapted for use with many forms of spouts difiering from the one here shown.

Fig. 7 illustrates a spout similar to Fig. 4 but with the hinge lug 2 attached to the top part A of the spout instead of to the wing B; Thi lug, when bent at right angles downward on the dotted line so as to be flush with the lower edge of the part A serves the same purpose as the correspond ing part in Figs. 1 and 2. The side extension of this lug may be let into the edge of wing B as shown at b. I

Fig. 8 shows a blank of a single angle spout of triangular form similar to those already described, but adapted to be used in a container opening like that of 3., but without the supporting shoulder 4. This shoulder 4 is objectionable in that it ohstructs the opening when pouring and furnishes a place for lodgment of the material thus obstructing the closing of the spout, and is liable to be bent downward too much or broken oil. The construction shown (Fig. 8) provides a lug 10 struck out of the wing B which rests upon the surface of the container as shown in Fig. 10. The other side of the hinge edge portion may be supported by the uncut portion of the container shown at 12, Fig. 3, or may be provided with a similar lug 10' as shown in dotted lines Fig. 8. The lug 1O taken from wing B leaves an opening in that part which it is emme necessary to close and the extension 11 of wing B is used for this purpose by folding it downwardly and up against wing B. Since the part 11 uses up the material employed in Fig. 7 for a portion of lug 2, this lug is formed from an extension of part A and the lateral tongue is folded on itself at the dotted line and thus forms an extension similar to the lateral extension of this lug in Fig. 7 Another feature of this construction is the flange Z) which is bent upward at right angles to the part B and form an extended surface for maintaining the spout in its endwise position. The container is cut away as shown at b, Fig. 10, to accommodate this flange.

Figs. 9, 10 and 11 show the construction just described applied to a double angle spout having the wings B and C and a rectangular top A. The similarity is obvious and the drawing will be readily understood by reference to the description given of Fig. 8 without further description, The parts 2 and 10 and the flange 10 in th1sconstruction are made in pairs instead of single parts. Tn this construction the stop 3 1s omitted and the turned up ends of the flanges Z) constitute the outward stop asshown at f. 1 The opening in the container 1s 1nd1cated by the dotted lines in Fig. 10. It s obvious that the packing-lining shown in connection with the single angle spout is applicable to this double angle spout.

Tt is obvious that further variations of construction may be employed without departing from the spirit of my inventlon, and

do not wish to be limited to the constructions shown.

What T claim is:
